STMicroelectronics reveals single-chip antenna-matching ICs for easier, faster design with Bluetooth LE SoCs and microcontrollers

Tue, Feb 07, 2023

STMicroelectronics has extended its range of single-chip antenna-matching ICs that simplify RF-circuit design with two new devices optimised for BlueNRG-LPS system-on-chip ICs (SoCs) and STM32WB1x and STM32WB5x wireless microcontrollers.

The MLPF-NRG-01D3 for BlueNRG-LPS and MLPF-WB-02D3 for STM32WB integrate the complete filtering and impedance-matching network needed for best RF output power and receiver sensitivity with an external antenna. Each has 50Ohm nominal impedance on the antenna side. The chip-scale package has a minuscule footprint, 0.4mm bump pitch and a profile of only 630micro after reflow soldering. Also featuring a 2.4GHz low-pass filter, ST’s antenna-matching ICs ease compliance with worldwide radio regulations, including FCC, ETSI, and ARIB specifications.

The circuit elements are fabricated on a glass substrate leveraging ST’s integrated passive device (IPD) technology, which, the company claimed, minimises insertion losses and outperforms circuits built with discrete components. Integration on the same die is said to ensure consistent component parameters for end-product quality. In addition, ST’s IPDs help accelerate time to market, reduce bill-of-materials costs and miniaturise circuit dimensions.

The BlueNRG-LP and Blue NRG-LPS SoCs and STM32WB1x and STM32WB5x contain ST’s energy-efficient 2.4GHz radio IP and come with royalty-free protocol stacks and dedicated software tools. They help developers quickly design state-of-the-art wireless products, even without having extensive RF-design skills. Both provide on-chip features such as memory, peripherals, communication interfaces, power regulation and advanced hardware security including encryption, memory protection and public key acceleration (PKA).

BlueNRG-LPx SoCs can be used in standalone or network processor applications and support Bluetooth Low Energy 5.3 features including point-to-point and mesh communications, advertising extensions and direction finding.

The MLPF-NRG-01D3 IPD is compatible with all variants, comprising the BLUENRG-3x5Vx, BLUENRG-3x5Ax and BLUENRG-332xx in UFQFPN and WLCSP packages.

The STM32WB5x and STM32WB1x MCUs are Bluetooth 5.3, Zigbee 3.0 and OpenThread certified and feature an Arm Cortex-M4 core for application processing with a Cortex-M0+ dedicated to managing the radio. They are available in WLCSP and UFBGA packages that connect directly to the MLPF-WB-02D3 IPD. A different IPD is available for other MCU variants in UQFN and VQFN packages.

The MLPF-NRG-01D3 and MLPF-WB-02D3 single-chip antenna-matching ICs are available from $0.14 for orders of 1,000 pieces.

nRF7002 companion IC and development kit create low power Wi-Fi 6 IoT

Thu, Feb 02, 2023

The first IC in Nordic Semiconductor’s Wi-Fi product family is the nRF7002 Wi-Fi 6 companion IC. The low power Wi-Fi 6 companion IC provides seamless dual band (2.4 and 5.0GHz) connectivity. The nRF7002 IC can be used with Nordic Semiconductor’s nRF52 and nRF53 series multi-protocol SoCs and the nRF9160 cellular IoT (LTE-M / NB-IoT) system in package (SiP), but can be used in conjunction with non-Nordic host devices.

In IoT applications, Wi-Fi 6 has power efficiency gains for battery power Wi-Fi operation and management in smart home products, industrial sensors, asset trackers, and wearables. They also contribute to the management of large IoT networks comprising hundreds of devices, said Nordic Semiconductor.

According to Svein-Egil Nielsen, CTO and executive vice president of R&D and Strategy at Nordic: “This highly integrated and flexible solution will empower developers to create new, innovative Wi-Fi 6-enabled products. Supported with the nRF7002 DK and the award-winning nRF Connect [software development kit], combined with Nordic’s . . . technical support, I believe it has never been easier to develop great Wi-Fi products.”

“The nRF7002 is designed to work alongside Nordic’s nRF52 and nRF53 Series making it a perfect fit for Matter, a smart-home standard backed by Amazon, Apple, Google, Nordic, Samsung, and hundreds of other companies,” explained Finn Boetius, product marketing engineer with Nordic. “The introduction of the IC and the nRF7002 DK now makes it easy for developers to get started on Matter and any other Wi-Fi based applications.” Matter uses Thread and Wi-Fi for data transport, and Bluetooth LE for commissioning.

The nRF7002 brings low power and secure Wi-Fi to the IoT. The dual-band IC complies with Station (STA), Soft Access Point (AP), and Wi-Fi Direct operation, and meets the IEEE 802.11b, a, g, n (Wi-Fi 4), ac (Wi-Fi 5), and ax (Wi-Fi 6) standards. The product also offers co-existence with Bluetooth LE, Thread and Zigbee.

The nRF7002 supports target wake time (TWT) a key Wi-Fi 6 power saving feature. Interfacing with a host processor is done via serial peripheral interface (SPI) or quad SPI (QSPI). The IC offers a single spatial stream, 20MHz channel bandwidth, 64 QAM (MCS7), OFDMA, up to 86Mbits per second PHY throughput, and BSS (base service set) colouring.

In addition to general IoT applications and Matter, the nRF7002 implements low power SSID-based Wi-Fi location when used with Nordic’s nRF9160 SiP and the company’s nRF Cloud Location Services. SSID-based Wi-Fi location supplements GNSS- or cell-based location by providing accurate positioning indoors and in places with a high density of Wi-Fi access points.

The introduction of the nRF7002 is accompanied by the launch of the nRF7002 DK, a development kit for the Wi-Fi 6 companion IC. The DK includes an nRF7002 IC and features an nRF5340 multi-protocol SoC as a host processor for the nRF7002. The nRF5340 embeds a 128MHz Arm Cortex-M33 application processor and a 64MHz high efficiency network processor. The DK supports the development of low-power Wi-Fi applications and enables Wi-Fi 6 features like OFDMA (orthogonal frequency-division multiplexing), beamforming, and TWT (target wake time). The DK includes Arduino connectors; two programmable buttons; a Wi-Fi dual-band antenna and a Bluetooth LE antenna, and current measurement pins.

The nRF7002 companion IC and nRF7002 DK are available now from Nordic’s distribution partners.

Barometric pressure sensor tracks altitude in harsh conditions

Tue, Jan 10, 2023

Barometric pressure sensors are a key component in fitness tracking wearables, to determine altitude. Bosch Sensortec has introduced the BMP585 robust barometric pressure sensor that can be used under water and in harsh environments.

It has a liquid-proof gel cover, which means it can be used in wearables that will be exposed to water or other liquids, including salt water and chlorinated water in swimming pools. It includes all the features of Bosch’s existing BMP581 pressure sensor with robustness and low power consumption ensures long battery life in wearables, hearables, and portable applications.

The sensor measures a change in height of just a few centimetres. It can therefore detect movements in fitness training down to the level of individual pull-ups or push-ups. “At the same time, users do not have to worry about environmental conditions – thanks to its ruggedness,” said Dr. Stefan Finkbeiner, CEO at Bosch Sensortec.

The BMP585 provides reliable mapping data for distance travelled and meters of altitude for hiking or running trips, thus supporting GPS data and enabling accurate localisation and navigation.

With its resistance to water and chemicals, the BMP585 is also suitable for a variety of industrial use cases such as liquid-level detection. The seal blocks access to dust for clog detection in home appliances such as vacuum cleaners.

The BMP585 provides excellent relative accuracy of ±0.06hPa and typical absolute accuracy of ±0.5hPa. The BMP585 has a typical temperature co-efficient offset (TCO) of just ±0.5Pa/K and low RMS noise of 0.08Pa at 1000hPa (typical). Long-term drift over 12 months is only ±0.2hPa.

Typical current consumption of just 1.3 microA at 1Hz data rate substantially extends battery life, said Bosch Sensortec. The BMP585 offers an I2C, I3C and SPI digital, serial interface.

The BMP585 is provided in a compact nine-pin LGA package with a metal lid, measuring just 3.25 x 3.25 x 1.86 mm³, small enough to use in smartwatches and other wearables.

The BMP585 is available in Q2 2023.
